Mikroelektronika MIKROE-2841 Fan 3 Click Board - MIC29152, Fan Speed Control

Technical description of the product (MIKROE-2841):

A fan is a simple device that creates a flow within some fluid – such as air – causing heat accumulated in one section of the fluid to move away from the heat source, effectively cooling the affected area. The faster the fan rotates, the faster the fluid moves. This movement causes an audible noise, which is one of the most obvious reasons why fan speed control is needed, especially when the fan cools electronic components, such as a personal computer. The Mikroelektronika MIKROE-2841 Fan 3 Click Board is the perfect choice for speed control and operates in seven discrete speed steps. Unlike PWM regulation, which can sometimes cause the infamous coil whining effect on some fan types, this Click Board outputs the selected voltage via the MIC29152 voltage regulator from Microchip, driven through the MIC74 – a serial to parallel I/O expander and a fan controller from the same company, keeping it constant at the output. The Fan 3 Click Board works with 12V to 25V on its input connector and is suitable whenever a noiseless solution with variable fan speed is needed, for example – cooling electronic components with minimal possible noise produced.
